Cronenworth (concussion) will begin a rehab assignment with Triple-A El Paso on Thursday.
Cronenworth has been on the concussion injured list since mid-April when he was struck in the chin by a pitch. With his symptoms finally abated, he's been cleared to test things out in a game setting. The length of Cronenworth's rehab assignment could depend on how he looks and feels, but since he's missed so much time, he'll likely need several games to knock off the rust.
